    Steel is generally divided into four categories, profiles, plates, building materials, and pipes.

    Among them, the material of profiles and plates is mainly classified as Q235B, Q345B and Q355B, while the main material of building materials is HRB400E, and the material of pipes is mainly Q235B. The types of profiles are H-beam, I-beam, channel steel, and angle steel. Among them, the plates include medium and heavy plates, pattern plates, pattern rolls, and open plates.

    Classification:

    According to the use, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel can be divided into two types: building structural steel and machine-made structural steel.

    According to the carbon content, carbon steel can be divided into low carbon steel (WC), medium carbon steel (WC) and high carbon steel (WC>. According to the phosphorus and sulfur content, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur) and high-grade high-quality steel (lower phosphorus and sulfur).

    Generally, the higher the carbon content in carbon steel, the higher the hardness and higher the strength, but the plasticity is reduced.

    Steel plate is a commonly used building material product in our construction industry, among which high-strength steel plate is often used in power station equipment, mining machinery and bridges and other buildings with high-quality performance and comprehensive force. However, many people don't know much about high-strength steel plates, so what are the models of high-strength steel plates? How to choose steel?

    What are the models of high-strength steel plates:

    High-strength steel plates are divided into Q390, Q420, Q460, Q550, and Q690 models, which have the characteristics of high strength and strong welding performance, so they are often used in various large weldments. However, the microalloying elements contained in different types of steel plates are different, and the higher the microalloy content, the greater the strength of the steel, and thus the carbon content in the steel will also increase.

    How to choose steel?

    1. First of all, when buying steel, it is necessary to see whether the steel is folded, that is, there are many folds on the longitudinal surface of the steel, and these folds are mainly due to the fact that the manufacturer in order to pursue efficiency, the amount of pressure is too large to produce ears, so that it will be formed when rolling in the next process, and this steel is easy to crack and break in use.

    2. Secondly, when purchasing steel, it is necessary to see whether there is a hemp surface on the surface of the steel, if there is, it means that the steel is of inferior quality, because the manufacturer uses excessive rolling groove rolling in order to reduce costs. In addition, if there is scarring on the surface of the steel, it is not recommended to buy it, mainly because the steel material content is not pure, or the manufacturer's production equipment is inferior, and it is easy to stick to the steel, which causes the scarring phenomenon after the roll.

    3. Finally, when purchasing steel, we should also pay attention to the cracks on the surface of the steel, and the reasons for the formation of cracks are mostly due to the use of porous adobe in the manufacture of the manufacturer, coupled with the effect of thermal expansion and cold contraction, so that the rolled steel has a large leakage crack.

    Summary: The above is the introduction of high-strength steel plate models and how to buy steel related content, I hope to help friends in need, if you need to know more about related knowledge in the later stage, welcome to pay attention to Qeeka Home.
